We're dividing 72929097 by 645 
We want to divide 72929097 by 645.

Let's proceed to step 1:
If we divide 7 by 645, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 645

Moving on to step 2:
645 goes into 72 0 times with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Take the next digit (9) from the dividend and append it to 72, then repeat: 729 / 645

Let's proceed to step 3:
729 divided by 645 is 1 with a remainder of 84.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 645 from 729, we get 84.
Bring next digit (2) of the dividend behind the 84 and repeat the process: 842 / 645

Step 4:
The number 645 fits into 842 1 times, leaving a remainder of 197.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 645 from 842 leaves us with 197.
Fetch the next digit (9) from the dividend, attach it to 197 and continue: 1979 / 645

Let's proceed to step 5:
645 can be fit into 1979 3 times, resulting in a remainder of 44.
Write down 3 as next digit of the result. 
Result so far: 113.0
Subtracting 1935 from 1979 leaves us with 44.
Take the next digit (0) from the dividend and append it to 44, then repeat: 440 / 645

Let's proceed to step 6:
When dividing 440 by 645, we get 0 with a remainder of 440.
Put 0 as the next digit of the answer. 
Result so far: 1130.0
Subtracting 0 from 440 leaves us with 440.
Include the next digit (9) from the dividend after 440, then repeat: 4409 / 645

Moving on to step 7:
When dividing 4409 by 645, we get 6 with a remainder of 539.
Use 6 as the next digit of our solution. 
Result so far: 11306.0
Subtracting 3870 from 4409 leaves us with 539.
Bring next digit (7) of the dividend behind the 539 and repeat the process: 5397 / 645

Let's proceed to step 8:
645 goes into 5397 8 times with a remainder of 237.
The next digit of our result is 8. 
Result so far: 113068.0
Subtracting 5160 from 5397 leaves us with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Step 9:
The number 645 fits into 2370 3 times, leaving a remainder of 435.
Put 3 as the next digit of the answer. 
Result so far: 113068.3
The remainder is 435 after subtracting 1935 from 2370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Step 10:
4350 divided by 645 is 6 with a remainder of 480.
Put 6 as the next digit of the answer. 
Result so far: 113068.36
Subtracting 3870 from 4350 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 11:
The number 645 fits into 4800 7 times, leaving a remainder of 285.
The number 7 becomes the next digit in our result. 
Result so far: 113068.367
Subtract 4515 from 4800 to get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Moving on to step 12:
The number 645 fits into 2850 4 times, leaving a remainder of 270.
Record the quotient 4 as the next digit in the result. 
Result so far: 113068.3674
Deduct 2580 from 2850 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Advancing to step 13:
645 goes into 2700 4 times with a remainder of 120.
Use 4 as the next digit of our solution. 
Result so far: 113068.36744
The remainder is 120 after subtracting 2580 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final result is 113068.36744 with a remainder of 0.00012.
